In an embodiment, as shown in fig. 3, fig. 3 shows a flow of implementing a charging method for multiple charging guns according to an embodiment of the present invention, the flow is applied to a power control module of a charging device for multiple charging guns as described above, and the process thereof is detailed as follows:
s101: acquiring the required power of a target charging gun; the target charging gun is any one of the first charging gun group 10 and the second charging gun group 20;
s102: and if the required power of the target charging gun is greater than the available output power of a target power supply module, controlling the bridging contactor Kq to be closed, wherein the target power supply module is a power supply module corresponding to the target charging gun.
In this embodiment, the available output power of the target power module is the total output power of the idle power modules in the target power module.
As can be seen from the above embodiments, in the present embodiment, the switching state of the bridging contactor Kq can be adaptively controlled according to the required power of the first charging gun group 10 and the required power of the second charging gun group 20, so as to change the output power of the first charging gun group 10 and the output power of the second charging gun group 20, and improve the charging efficiency of the charging device.
In one embodiment, before S102 in fig. 3, the method may further include:
s201: if the target power supply module has an idle power supply module, selecting the idle power supply module in the target power supply module as a target power supply module according to the required power;
s202: and closing the power contactor Kp corresponding to the target power supply module.
In this embodiment, the power module includes two states, namely idle and non-idle, where the idle state is a state without power supply, and the non-idle state is a state in which power is being supplied to the charging gun.
And if the output switch of the target charging gun is closed, closing the power contactor Kp of any idle power module in the target power module, so that one power module supplies power for the target charging gun, and changing the state of the power module into non-idle state. If the output power of the power supply module is smaller than the output power of the target charging gun, an idle power supply module is preferentially selected from the target power supply module, and if the target power supply module does not have the idle power supply module, the bridge connection contactor Kq connected with the target charging gun is closed, so that the idle power supply module in the opposite power supply module is used for charging the target charging gun.
In an embodiment, the S202 specifically includes:
s301: selecting any idle power supply module in the target power supply module as a target power supply module, and changing the state of the target power supply module into non-idle state;
s302: if the required power is greater than the total output power of the current target power supply module, repeating the steps from S301 to S302 until the required power is less than or equal to the total output power of the current target power supply module.
In one embodiment, S102 in fig. 3 includes:
and if the required power of the target charging gun is greater than the available output power of the target power supply module, the charging gun connected with the target charging gun through the bridging contactor Kq is not in a use state, and an idle power supply module exists in another power supply module except the target power supply module, controlling the bridging contactor Kq connected with the target charging gun to be closed.
In this embodiment, the states of the charging gun include a used state and an unused state, and if the output switch corresponding to the charging gun is closed, the charging gun is in the used state, and if the output switch corresponding to the charging gun is open, the charging gun is in the unused state.
As shown in fig. 2, when the charging gun P1 is the target charging gun and the charging gun P5 is in the use state, the bridge contactor Kq cannot be closed. If the charging gun P1 is a target charging gun and there is no idle power module in the opposite side power module, the bridging contactor Kq cannot be closed, and the power control module controls the bridging contactor Kq to be closed only when the required power of the charging gun P1 is greater than the available output power of the power module corresponding to the charging gun P1, the charging gun P5 is not in use, and there is an idle power module in the opposite side power module.
In an embodiment, after S102, the charging control method for multiple charging guns further includes:
subtracting the available output power of the target charging module from the required power to obtain a power difference value;
selecting an idle power supply module in another power supply module except the target power supply module as a target power supply module according to the power difference;
and closing the power contactor Kp corresponding to the target power supply module.
In the opposite side power module, a method of judging whether the total output power of the target power module is greater than the required power or not is also adopted every time the power contactor Kp of an idle power module is closed until the total output power of the selected target power module is greater than the required power of the target charging gun, so that the output of the required power of the battery corresponding to the target charging gun is met.
In this embodiment, when the battery is connected for charging for the first time, the power module that needs to be closed may be directly determined according to the required power of the battery, and the corresponding power module is closed. If the required power of the battery rises in the charging process, the idle power supply module in the target power supply module is preferentially selected for supplying power, and if the total output power of the idle power supply module in the target power supply module cannot meet the required power added value of the target charging gun, the corresponding bridging contactor Kq is closed, and the power requirement of the target charging gun is met through the idle power supply module on the opposite side.
In one embodiment, when the required power of the battery corresponding to the target charging gun decreases, the power module of the opposite side power module is switched out preferentially, and then the power module of the local side power module is switched out until the output power of the currently connected power module meets the power requirement of the target charging gun.

the method comprises the following steps: selecting any idle power supply module in the target power supply module as a target power supply module, and changing the state of the target power supply module into non-idle state;
step two: and if the required power is larger than the total output power of the current target power supply module, repeatedly executing the first step to the second step until the required power is smaller than or equal to the total output power of the current target power supply module.
8. The charging control method of multiple charging guns according to claim 5, wherein the controlling the bridging contactor to close if the required power of the target charging gun is greater than the available output power of the target power module comprises:
and if the required power of the target charging gun is greater than the available output power of the target power supply module, the charging gun connected with the target charging gun through the bridging contactor is not in a use state, and an idle power supply module exists in another power supply module except the target power supply module, controlling the bridging contactor connected with the target charging gun to be closed.
9. The charging control method of a multiple charging gun according to claim 5, wherein after the control bridge contactor is closed, the method further comprises:
subtracting the available output power of the target charging module from the required power to obtain a power difference value;
selecting an idle power supply module in another power supply module except the target power supply module as a target power supply module according to the power difference;
and closing the power contactor corresponding to the target power supply module.
10. A terminal device comprising a memory, a processor and a computer program stored in the memory and executable on the processor, characterized in that the processor implements the steps of the method according to any of claims 5 to 9 when executing the computer program.
